Manchester United boss Erik ten Hag has hinted he wants to see their attack improved.
The Dutchman has been reflecting on his start at the club today.
"I hoped that we would be where we are now but it is better to ask after Sunday," he said.
"But if you go into the process then you can look at the analysis, make a reflection until today, one of the conclusions you can make about the front line there is a concern.
"I think we really made progress in football, pressing, play out from the back and also attacking. But the final third we have to improve but you also have to have numbers available and for so many games you need rotation, otherwise you don't keep the players fresh."
He said the club need "both" new players and ones returning to fitness, highlighting how he wants Alejandro Garnacho to continue his progress because United "need the numbers".
